    Beneficial Effects of Bioactive Compounds Obtained from Agro-Industrial By-Products on Obesity and Metabolic Syndrome Components
    (2022) Jeria, Nicolas; Cornejo, Sebastian; Prado, Gabriel; Bustamante, Andres; Garcia-Diaz, Diego F.; Jimenez, Paula; Valenzuela, Rodrigo; Poblete-Aro, Carlos; Echeverría González, Francisca Cecilia
    The generation of agro-industrial by-products is an economic and environmental problem. However, these raw materials could be a suitable source for obtaining bioactive compounds for technological or nutritional purposes. On the other hand, obesity and metabolic syndrome prevalence are in continuous growth. The classical approach of hypocaloric diet and exercise has shown little long-term adherence. Thus, there is an unending search for new strategies to prevent and treat obesity and related metabolic alterations. In that sense, the revalorization of agro-industrial by-products for functional foods and nutraceutical development has gained relevance. Pomegranate, onion, and grape by-products, among others, have been described as promising raw materials for bioactive compounds obtention. Nevertheless, scientific evidence on the effects of specific sources and bioactive compounds on obesity models and clinical trials is needed. This article aims to show available data from studies on the effect of bioactive compounds obtained from agro-industrial by-products on obesity and metabolic syndrome components.

    Exergames as a tool for improving muscular fitness, cardiorespiratory fitness, and body composition in children and adolescents: a systematic review
    Solar Figueroa, Vaitiare; Soto San Martín, Alejandro; Ferrero-Hernández, Paloma; Espoz Lazo, Sebastián Ignacio; Marín-Guajardo, Cecilia; Farías Valenzuela, Claudio; Poblete-Aro, Carlos
    Introduction: over 80% of children and adolescents fail to meet physical activity recommendations, leading to declines in muscular and cardiorespiratory fitness and rising obesity rates. Exergames—digital games requiring physical movement—are a promising tool to promote activity in youth.Objective: to determine the effects of exergames on muscular fitness, cardiorespiratory fitness,and body composition in children and adolescents.Methodology: a search was conducted in Web of Science, Scopus, CINAHL, and PubMed databases, including randomized controlled trials published in the last 10 years. Studies were excluded if they involved participants with disabilities or used exergames for rehabilitation orhospital-based interventions.Results: a total of ten studies were included: three out of five studies reported improvementsin muscular fitness, seven out of nine in cardiorespiratory fitness, and five out of nine in bodycomposition. The most effective interventions occurred 2–3 times per week, for 40–60 minutesper session, over at least 12 weeks.Discussion: while outcomes are promising, differences in study design, duration, and assessment tools may have affected consistency across results.Conclusion: exergames appear effective for improving health-related fitness in children and adolescents, providing a fun and accessible way to increase physical activity through technology.
